Description

Technical Field

[0001] The invention relates to a vegetation restoration device and belongs to the technical field of vegetation restoration. Background Art

[0002] For deserts with arid desert climate, precipitation is scarce throughout the year, and there are many windy and sandy weather in all seasons. There are more than 220 days of dust weather each year, of which dense dust (sandstorm) weather is about 60 days. Its general characteristics are drought and little rain, strong evaporation, sufficient sunshine, abundant heat, frequent disastrous weather such as strong winds, sandstorms, blowing sand, and dust, serious sand damage, shortage of water resources, uneven regional distribution, etc., which seriously restricts agricultural development. However, due to the characteristics of long sunshine hours and strong solar radiation, the area on the edge of the desert is one of the areas with the richest solar energy resources and an important area for large-scale development and utilization of solar energy in my country. Therefore, the combination of photovoltaics and sand control can not only achieve the transformation from "sand advancing and people retreating" to "people advancing and sand retreating", but is also an effective way to achieve the transition from sand prevention and control to scientific utilization. The surface-distributed solar panels can effectively provide shade and protection for the vegetation underneath them, and the surface of the solar panels in the desert with frequent sandstorms needs to be washed frequently, and the water from the washing can be used to irrigate the vegetation planted under the photovoltaic panels. This sand control model has gradually become one of the scientific and efficient sand control measures that conforms to the actual situation of the Shatin area in the new era. It can form a virtuous circle that takes into account both ecological protection and economic development, and can effectively restore the vegetation of photovoltaic power plants.

[0003] However, there are still some shortcomings in the work of restoring vegetation in photovoltaic power plants: first, it is necessary to manually dig holes in the sand for planting, and to manually replenish water or nutrient solution for the plants in each hole, which has low work efficiency and increases the labor intensity; second, the solution tank mixed with fertilizer and nutrient solution is difficult to carry and move, and during the irrigation process, the solution in the solution tank is prone to precipitation, resulting in uneven concentration of nutrient solution applied to the plants, which can easily cause the plants to die due to too little or too much nutrient solution.

Before performing vegetation restoration work, firstly, the water, fertilizer or nutrient solution required for vegetation restoration is stored in the solution tank 1 as needed, and the mobile vehicle 3 is moved to the sandy land where the photovoltaic power plant is distributed.

[0056] S2. When performing the work of restoring vegetation in the sand, the electric hydraulic push rod 4 is started. The electric hydraulic push rod 4 lifts the lifting frame 6 through the hydraulic rod inside it. When the lifting frame 6 moves downward, the lifting frame 7 slides down between the two vertical plates 52, and the lifting frame 7 drives the Z-shaped seat 83 to slide down, thereby driving the linkage gear 84, the first bevel gear 89, the second bevel gear 82, the drill rod 86 and the spiral leaf 87 to slide down, so that the drill rod 86 and the second bevel gear 82 slide down along the outer wall of the connecting pipe 81. During the downward movement of the linkage gear 84, under the action of the third rack 91, it can rotate by itself, thereby driving the second bevel gear 82 to rotate by itself, and then driving the drill rod 86 and the spiral leaf 87 to rotate through the first bevel gear 89, and drilling holes in the sand through the downward and rotating drill rod 86 and spiral leaf 87. At this time, the blocking ball 851 can block the lower port of the through groove 88 under the squeeze of the sand and the elastic force of the connecting spring 852.

[0057] At the same time, during the downward movement of the lifting frame 6, the second rack 24 can be driven to move downward. Under the action of the transmission gear 23, the first rack 21 moves upward, thereby driving the lifting plate 27 to slide upward in the inner cavity of the solution tank 1 through the L-shaped connecting rod 26. The solution stored in the solution tank 1 shuttles through the through hole 28, so that the solution in the solution tank 1 can be shaken and mixed to avoid precipitation of the solution.

[0058] S3. After the drilling is completed, the electric hydraulic push rod 4 drives the lifting frame 6 to move upward, and the lifting frame 6 drives the drilling and injection module 8 to move upward through the lifting frame 7. At the same time, the lifting frame 6 can drive the second rack 24 to move upward, and under the action of the transmission gear 23, the first rack 21 and the L-shaped connecting rod 26, it can drive the lifting plate 27 to move downward. The downwardly moved lifting plate 27 can shake and mix the solution inside the solution tank 1, and when the lifting plate 27 is about to contact the bottom of the inner cavity of the solution tank 1, the lifting plate 27 will fit with the baffle 15, so that the through hole 28 on the lifting plate 27 can be blocked. As the lifting plate 27 continues to move downward, the solution retained at the bottom of the solution tank 1 can be squeezed into the connecting pipe 81 and transported to the through groove 88 inside the drill rod 86 through the connecting pipe 81. Under the action of water pressure, the sealing ball 851 overcomes the elastic force of the connecting spring 852 and moves away from the bottom end of the drill rod 86, so that the solution inside the through groove 88 can be discharged into the sand hole drilled by the drilling and injection module 8 through the lower port of the through groove 88.

[0059] S4, planting the prepared vegetation in the sand holes after the solution is applied, and then moving the mobile vehicle 3 to drill holes and irrigate the next sandy land.

[0060] The present invention arranges a solution tank 1, a lifting module, a mixing and pressurizing module 2 and a drilling and injection module 8 on a mobile bracket, utilizes the descending process of the lifting module to drive the mixing and pressurizing module 2 to stir the solution in the solution tank 1, and the drilling and injection module 8 to drill a hole in the ground, and utilizes the ascending process of the lifting module to drive the mixing and pressurizing module 2 to squeeze the solution in the solution tank 1, so that the solution is introduced into the borehole through the drilling and injection module 8, thereby realizing automatic drilling and automatic irrigation.
